NVM is a Node Version Manager tool. Using the NVM utility, you can install multiple node.js versions on a single system. You can also choose a specific Node version for applications. It also provides an option to auto-select the node version using the .nvmrc configuration file.

install nvm
    cd ~/asmara/workbench
    curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash 
    source ~/.profile 
    nvm --version
install node and npm using nvm 
    install the latest
        nvm install node  
    switch to specific version 
        nvm install node 
        nvm install 14.17.6 
    node --version 
    npm --version 
uninstall the global Angular CLI 
    npm uninstall -g @angular/cli 
install the latest angular cli globally
    npm install -g @angular/cli@latest

!!! installing a specific version of angular client locally worked but the application did not run so it was abondanded !!!
